The answer is 1.48 x 10^8. This is because 148 million is represented as 148 000 000 and it takes 8 decimal places to make it 1.48. Hope this helps!
Answer is: C. exothermic reactions.
For example, the Haber process is procedure for the production of ammonia, in this process atmospheric nitrogen (N₂) is converted to ammonia (NH₃) and energy is released:
N₂ + 3H₂ ⇄ 2NH₃ ΔrH = -92 kJ/mol.
There are two types of reaction: endothermic reaction (chemical reaction that absorbs more energy than it releases) and exothermic reaction (chemical reaction that releases more energy than it absorbs).
Below are the choices that can be found from other sources:
<span>A) elements
B) ions
C) molecules
D) neutrons
the answer is ions.
</span>A Star<span> and hence our Sun, is an almost entirely ionized ball of </span>plasma<span>, consisting of electrons and ions, in which there is hardly any gas (neutral atoms). The movement of the </span>plasma<span> produces strong magnetic fields and corresponding electric currents.</span>
I think it’s B but I’m not really sure
